ている。2. Description of the Related Art A dry sump type gear transmission is, as the name implies, a gear transmission having no oil reservoir inside the gear transmission. Unlike a conventional splash type, a dry sump type gear transmission is forcibly lubricated by an oil pump. The oil to be lubricated is sprayed directly onto the bearing portion, the meshing surface of the gear, the conical surface of the synchronous meshing clutch, etc., and is cooled by an oil cooler. No large-capacity oil pan is provided at the bottom of the case of the gear transmission. The dry sump type is suitable for lubrication under high speed and high load, and is also used for a gear transmission of a racing vehicle and an internal combustion engine of an aircraft.

４２へ戻す手段がない。という問題がある。A conventional dry sump type gear transmission as disclosed in FIGS. 2 and 3 is known. In the dry sump type gear transmission disclosed in FIG. 2, oil collected at the bottom of the case of the gear transmission 42 is sucked from a strainer 43 by an oil pump 44 and discharged through a pipe 45 to an oil sump 46. The oil sump 46 is disposed above the case of the gear transmission 42 and passes through a pipe 47 to an oil cooler (oil cooler).
48, and the oil cooled by the oil cooler 48 is gravity driven.
Pipe 49, output shaft of gear transmission (see output shaft 4 in FIG. 1)
Through the internal passages, the oil is supplied to each oil supply section 50 such as a bearing section, a gear meshing section, and a synchronous meshing clutch. Since the above-described dry sump type gear transmission does not have a sufficient oil reservoir, it is impossible to lubricate the gear transmission 42 when the oil pump 44 or the like fails. There is no means for returning oil to the gear transmission 42 even if the volume of the oil reservoir 46 is increased. There is a problem.

である。[0004] In the dry sump type gear transmission disclosed in FIG. 3, an oil sump 51 is disposed above the gear transmission 42, and oil collected at the bottom of the case of the gear transmission 42 is subjected to oil from a strainer 43. It is sucked by the pump 44 and discharged through the pipe 45 to the oil reservoir 51. Air (bubbles) mixed into the oil is separated in the oil reservoir 51, the oil in the oil reservoir 51 is sucked from the strainer 52 by the oil pump 53, and the oil cooler 4

すぎたりする恐れがある。The above-described dry sump type gear transmission has a sufficient oil reservoir 51 and an oil pump 53 for returning oil to the gear transmission 42, so that the oil is supplied even when the oil pump 44 or the like fails. There is an advantage that it can be returned to the gear transmission 42. However, air (bubbles) may enter the tube 45. Two oil pumps 44 and 53 are required. There is such a problem. Having two oil pumps 44 and 53 not only increases the cost but also makes it difficult to keep the oil level of the gear transmission 42 constant. That is, it is difficult to completely equalize the discharge amounts of the oil pump 44 for suction and the oil pump 53 for supply, and the oil pumps 44 and 53 suck air and the oil level of the gear transmission 42 rises too high. May be.
